His heart went KABOOM!

Really, is anyone shocked that Billy Mays most likely died of a heart attack?  After all, we have hours of footage of him getting totally worked up over the smallest things, like throwing a ball of detergent into the wash or shoving a hook through drywall.  His adrenaline levels would be pushed to the edge at just the idea of chopping onions with a plastic gadget instead of a knife. 

All that excitement was bound to catch up with him.
